A comparison between amniotic fluid index and the single deepest vertical pocket technique in predicting adverse outcome in prolonged pregnancy

Abstract

oligohydramnios is more frequently diagnosed using AFI than SDVP, consequently determining a higher rate of induction of labor. Moreover, perinatal outcome in prolonged induced pregnancies is not affected by oligohydramnios.

Determinants of Maternal and Neonatal Outcomes of Oligohydramnios After 37+0 Weeks of Gestation in Mekelle Public Hospitals, Northern Ethiopia

“…Odds of experiencing composite adverse maternal outcome nearly doubles, triples and quadraples in women with hypertensive disorders of pregnancy compored to those whithout, oligohydramnios at early term gestation compared to those at full term and in those who are not married compared with those who are married respecrtively but these variables did not show an actual signi cant stastistical trend [ Table 8]. The rate of oligohydramnios [2.6%] in the present study is in agreement with other studies done in Ethiopia, India, Nigeria, Israel and USA which reported similar rates [1,7,36,37].…”

“…Different tests have been proposed to determine amniotic uid volume as mean of evaluation of fetal wellbeing [12]. Amniotic uid index [AFI] and single deepest pocket [SDP] are the most-used semiquantitative techniques.…”

Evaluation of Amniotic Fluid Volume using Single Deepest Pocket Method

“…6 Obstetricians plan delivery by induction of labor or caesarean section after diagnosis of decreased amniotic fluid volume at term, to prevent an adverse pregnancy outcome. 7 The method of amniotic fluid volume estimation using the amniotic fluid index increased the number patients who were diagnosed with oligohydramnios and polyhydramnios which in turn leads to an abnormal fluid volume when compared with the single largest pocket measure. In a study by Alfirevic 8 et al 490 patients where considered showed that a significantly greater number of patients were considered to have oligohydramonos when amniotic fluid index was used than with single largest pocket.…”

Perinatal outcomes following labor induction with dinoprostone in pregnancies with borderline amniotic fluid index at term: A clinical observation study

“…Despite considerable doubts regarding the best noninvasive method of estimating amniotic fluid volume and its effectiveness in predicting perinatal outcomes, the AFI is still preferred in routine clinical practice . Furthermore, the relationship between borderline AFI and perinatal outcomes was widely studied, also remains controversial.…”
